de la Sovera, Victoria;Lopez, Gloria V.;Porcal, Williams research published 《 Synthetic Study of 5-Hydroxymethylfurfural in Groebke-Blackburn-Bienayme Reaction》, the research content is summarized as follows. The reactivity of 5-hydroxymethylfurfural (5-HMF), a renewable platform chem., as the aldehyde component in the Groebke-Blackburn-Bienayme (GBB) multicomponent reaction was explored. Given the limited stability of 5-HMF under conventional conditions used for this reaction, acidic milieu in combination with high temperature or long reaction times, factors which influence the course of the reaction (solvent, catalyst, time, and temperature) within the guidelines of previously reported green reaction conditions were explored. Mild conditions and short reaction times were achieved to obtain good conversion and selectivity values. The reaction scope was exemplified by preparing a small compound library based on the optimized conditions varying the amidine such as 1,3-thiazol-2-amine, pyridin-2-amine, pyrazin-2-amine, etc. and the isocyanide RNC (R = t-Bu, cyclohexyl, C(O)OEt, benzyl) component.
